And people would buy toys with lead paint in them too if the price was low and they weren't aware of the risks of lead paint. Does that mean the regulations preventing them are wrong?
Children are assumed to lack the capacity to make intelligent decisions for their well-being. They receive both additional protections, and are denied most of the rights which are granted to adults. Regulating toys may hold up in that philosophy, in as much as they are intended for children. However, adults are still allowed to purchase products which contain lead, such as solder, because the assumption is they can adequately assess the risks, and have the right to decide accordingly.
Certainly, we can treat average citizens as too ignorant to tend for their own welfare, and provide state protection, but just as with children, these adults are being denied certain rights and freedoms in exchange. There are many proxies for this question, among them, whether people should be allowed to purchase firearms or drugs, even though they are capable of doing damage, depending on the decisions of the user.
Which is how the regulations came into effect in the first place -- the public was tired of getting into cabs that weren't insured or maintained properly.
The question is how necessary are the regulations, and, especially, how applicable the regulations which were written specifically for taxis in a different era are nowadays.
This is one of the major problems with government solutions--they have an awful lot of momentum. It's hard to make changes when changes are warranted.
Do I really care how well-maintained the transport car is? Why does it need to exceed rules established for cars in general? Are poorly maintained vehicles as much of an issue with modern automobiles as it was when the law was passed? Does the ability of users in Uber and Lyft to rate drivers completely solve the problem since they can vote down drivers with unpleasant or unreliable rides? Is it now so easy to flag down a new driver that the car breaking down is not a particular issue?
How important is a multimillion dollar insurance package? Is this actually improving the situation for people who would otherwise be walking or taking their own vehicles or a friend's vehicle without such a high insurance coverage? Would it possibly make more sense to transition to a system in which passengers carry insurance instead of drivers?
The situation is simply not the same as it was when these laws were passed. Back then, these laws provided possibly needed solutions. Now, if the problems they were intended to solve even exist, there may be better solutions. The question is whether the state is going to step in and forbid citizens from pursuing these solutions, on the premise the state is once-and-always-correct, or if we are going to let citizens experiment and make their own decisions.
